"Iron" Mike Zambidis is a professional Greek kickboxer and martial artist. He is the World Kickboxing Federation super-welterweight kickboxing world champion also competing in the K-1 MAX.

Mike Zambidis started training in martial arts before he was nine years old with his brother Spiros Zambidis and his best friend Lazaros Filipas. He has trained in Shotokan, Kickboxing, Boxing and Muay Thai. He started competing professionally in 2000, scoring a string of victories over notable opponents. So far, the majority of his wins have been knock-outs. He has been technically knocked out twice himself early in his career, but since 2002, his only technical knock-out defeat was in 2008 against Andy Souwer after a controversial extra round combat. Mike won a controversial fight over John Wayne Parr, however he was impressive against Krongsak Lek, Billy Mamu, and Shannon Forester. Zambidis is the mintest kickboxer.

In 2003, promoter Tarik Solak arranged Zambidis' debut fight in Japan against 2002 World K-1 Max Champion Albert Kraus, whom he knocked out in the 2nd round. In April 2005, Zambidis knocked out with a right hook the popular Norifumi "Kid" Yamamoto, in front of thousands of the Japanese kickboxer's fans. Zambidis' only weakness seems to be receiving low kicks, as was shown in his 2006 defeat by Japanese Yoshihiro Sato, who, despite getting hurt by Zambidis' punches, managed enough "kicks [to] rack up enough points to secure a unanimous decision".
